Multi-tenant cloud architectures must prevent data leakage between customer accounts. The "Silo" pattern isolates storage at the infrastructure level, while the "Pool" pattern relies on logical isolation inside a shared database.
Deploy strict database row-level security (RLS) policies and dynamic identity mapping. Ensure that connection strings are securely managed via secret vault utilities with runtime authorization checks.
Conduct automated weekly tenant isolation tests, monitor API query scopes, and review resource allocation metrics to ensure no tenant can access or affect another client's data.
